Abstract
Description
- The present disclosure relates to the field of wireless communication technologies, and in particular, to an antenna system and a mobile terminal.
- With 5G being the focus of research and development in the global industry, developing 5G technologies and formulating 5G standards have become the industry consensus. The ITU-RWP5D 22nd meeting held in June 2015 by International Telecommunication Union (ITU) identified three main application scenarios for 5G: enhance mobile broadband, large-scale machine communication, and highly reliable low-latency communication. These three application scenarios respectively correspond to different key indicators, and in the enhance mobile broadband scenario, the user peak speed is 20 Gbps and the minimum user experience rate is 100 Mbps. The high carrier frequency and large bandwidth characteristics unique to the millimeter wave are the main means to achieve 5G ultra-high data transmission rates.
- The rich bandwidth resources of the millimeter wave band provide a guarantee for high-speed transmission rates. However, due to the severe spatial loss of electromagnetic waves in this frequency band, wireless communication systems using the millimeter wave band need to adopt an architecture of a phased array. The phases of respective array elements are caused to distribute according to certain regularity by a phase shifter, so that a high gain beam is formed and the beam is scanned over a certain spatial range through a change in phase shift.
- The metal frame architecture is the mainstream solution in mobile phone structural design, providing better protection, aesthetics, thermal dissipation and user experience. However, due to the shielding effect of metal on electromagnetic waves, the radiation performance of the upper and lower antennas will be seriously affected, and the gain of the antenna will be reduced.
- Therefore, it is necessary to provide a new antenna system to solve the above problems.
- Many aspects of the exemplary embodiment can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
